Array/v5? Patented Dec. 2, 1930 UNETEDV'STATES CHARLES TILLBERG, or on oAGo; IrJLrnoIs DOOR-OPERATED sieNAn Application filed July 28, 1930. "Serial an. 471,171-

This invention relates to improvements in door operated signals and more particularly to door bells and strikers of that type adapted .for use upon doors that are opened and closed frequently, such as the doors of small retail stores, where it is desired to give the attendant, clerk or owner audible notice or warning of the arrival or entrance of a customer or other person. Small retail stores that ordinarily require the attention of but one or two clerks intermittently, the clerk or attendant retiring to the rear of the actual sales room between times,.can be advantageously served by audible signals of this nature.

One object is to provide a door bell and striker that is positive and efficient in operation, inexpensive to manufacture, and durable in use. A further'object is to provide a door oell and striker that is very easy to install, and that can be applied equally well to doors that open either to the right or left.

With the foregoing and other objects in Like reference characters denote corresponding parts throughout.

0 supported above the door in the path of a striker carried by the door, the striker coming in contact with the bell and ringing the same each time the door is opened or closed and thus giving audible warning to the attendant of the door movement. The striker is made adjustable so that in the more busy periods of the day when the attendant is kept in the store the striker may be manually moved downward with respect to the bell so The door bell and striker comprises a bell that it will not strike the same with the door movements. 1 a i Y The reference numeral 1 denotes a door and 2. that portion of the door casing above the door. To the casing 2 a pair of spaced diametrically opposed angular brackets 3,

4: are secured by rivets or fasteners-5,eac h bracketbeing formedwith a non-circular perforation 6, said perforations being diamet-i rically opposite each other and connected by the tubular bar 7, the ends thereof being fiattened slightly and secured in said perform tions 6 as shown quite-clearly in Fig. 3.

A-pair of opposed twin c'oilsprings 8, 9 encircle said bar 7 said springs being .materially larger at their adjacent than at their, remote ends which latter ends are made .fast to said bar, thel'arger ends of said springs being spaced apart'slightly andextending downwardly into engagement with an angu 79 larbell clamp 10 and securely clamped thereto by the metal yoke 11, the free ends 12 of said springs being bent upwardly against the yoke as shown in Fig. 2.

' The bell clamp is secured by rivet 13 to the top of the bell 14, said rivet extending into the bell and carrying the hammer 15. The rectangular striker 16 is formed with the longitudinal slots 17, 18 in a common vertical plane, an eye-bolt 19 extending through the slot 17 into the door and a screw 20 extending through the slot 18 into the door so that the striker is capable of manual adjustment vertically upon the door. As the bell 14 is disposed in the path. of movement of the striker when the same is in normal raised position, illustrated in Fig. 1, the striker will ring the belleach time the door is opened or closed. The bell is resiliently supported by the springs 8, 9 so that if the door is opened just enough to position the striker inside the bell the subsequent movement of the door will not break the bell as the striker is freed therefrom. When the striker is lowered a certain distance it will not contact with the bell as the door is opened or closed but will move back and forth below the bell.

What is claimed is 1. In a door-operated signal, a bell resiliently supported above the door, a slotted striker carried by the door and projecting thereabove for contact, in one position, With said bell, and fasteners disposed in the slotted portions of said striker whereby the same is adjustably secured to the door.

2. In a door-operated signal, a bell resiliently supported above the door, a striker for said bell formed With spaced vertical slots disposed in a common plane, and manually operable fasteners disposed in said slots for adjustably securing said striker to the door.

3. In a door-operated signal, a striker adjustably secured to the door 'and projecting thereabove, spaced brackets secured to the door casing above the door, a bar connecting said brackets, springs secured to said bar, and a bell carried by said springs and disposed in the normal path of movement of said striker.

4. In a door-operated signal, a striker adjustably secured to the door and projecting thereabove, spaced brackets secured to the door casing above the door, a bar connecting said brackets, opposed spaced coil springs encircling said bar, the remote ends of said springs being directly secured to the bar, the adjacent ends of said springs being relatively large and terminating in downwardly extending portions, and a bell supported directly by said last named spring ends in the normal path of movement of said striker.

In testimony that I claim the foregoing as my own I have hereto aifiried my signature.

CHARLES TILLBERG.
